Android中Sqlite中的最大列数

Question

实际上我的Database（Sqlite）中有11列，现在我将列数增加到15列，这会影响我的应用程序吗？如果是，那么可行的解决方案是什么？

Answer 1

i think it wont.

The default setting for SQLITE_MAX_COLUMN is 2000. You can change it at compile time to values as large as 32767. On the other hand, many experienced database designers will argue that a well-normalized database will never need more than 100 columns in a table.

so in your case 15 would not be an issue i think.

Answer 2

不，只要您有足够的内存，它就不会对应用程序产生影响。请在此处检查此链接： http : //www.sqlite.org/limits.html

Answer 3

It wont effect the application .....

Actually If the table grows vertically there will be performance problems...

But there wont be any effect if it grows horizontally....

Any how i prefer you to normalize the tables if there is any possibility...
